Is there a function that can cut words from a string that are small length e.g. "the, and, you, me, or" all these short words that are common in all sentences. i want to use this function to fill a fulltext search with criteria
before the method:
$fulltext = "there is ongoing work on creating a formal PHP specification.";
outcome:
$fulltext_method_solution = "there ongoing work creating formal specification."
$fulltext = "there is ongoing work on creating a formal PHP specification.";
$words = array_filter(explode(' ', $fulltext), function($val){
return strlen($val) > 3; // filter words having length > 3 in array
});
$fulltext_method_solution = implode(' ', $words); // join words into sentence
php >= 5.3. Also $words is array, implode it as you need. @user3485007
try this:
$fulltext = "there is ongoing work on creating a formal PHP specification.";
$result=array();
$array=explode(" ",$fulltext);
foreach($array as $key=>$val){
if(strlen($val) >3)
$result[]=$val;
}
$res=implode(" ",$result);
implode() ?
You can simply use implode, explode along with array_filter
echo implode(' ',array_filter(explode(' ',$fulltext),function($v){ return strlen($v) > 3;}));
or simply use preg_replace as
echo preg_replace('/\b[a-z]{1,3}\b/i','',$fulltext);
try this:
$stringArray = explode(" ", $fulltext);
foreach ($stringArray as $value)
{
if(strlen($value) < 3)
$fulltext= str_replace(" ".$value." " ," ",$fulltext);
}
Here is a working DEMO
Simply explode the string and check for the strlen()
$fulltext = "there is ongoing work on creating a formal PHP specification.";
$ex = explode(' ',$fulltext);
$res = '';
foreach ($ex as $txt) {
if (strlen($txt) > 3) {
$res .= $txt . ' ';
}
}
echo $res;
By using preg_replace
echo $string = preg_replace(array('/\b\w{1,3}\b/','/\s+/'),array('',' '),$fulltext);
This will also produce the desired results:
<?php
$fulltext = "there is ongoing work on creating a formal PHP specification.";
$fulltext = preg_replace('/(\b.{1,3}\s)/',' ',$fulltext);
echo $fulltext;
?>
